Amorphous Ni-Pd-Si ribbons were partially crystallized by relaxation treatment then secondary amorphous Ni-Pd-Si alloy powder prepared by mechanical milling. The surface states of amorphous and crystalline Ni-Pd-Si powders were studied by XRD, TEM, AES and ESCA spectra. The catalytic activities of amorphous and crystalline powders in hydrogenation of styrene was measured.The result shows that the catalytic activity of amorphous Ni-Pd-Si powder was higher than that of crystalline one by 6 times in hydrogenation of styrene.

Physics of Life Reviews

Commentaries by Philip W.T. Pong, Nongyue He, S.D. Liang, Tao Song, Yuri Gaididei and Sergey Volkov and Alexander Y. Grosberg on my review article (Pang, 2011 [1]) are answered. The validity of Davydov's mechanism of bio-energy transport, the completeness of theory, outstanding problems, the normalization and validity of wave function of the system in Pang' model as well as other related problems are elucidated in detail.
